I had to change from d-pump to D-pump 357-still the same guy. I consider myself well seasoned in this sport and this world of BB-I'm 24, at 220, 6' and 10%bf. I am at pretty high dosages of sust and test (1000 and over) I shoot only in the glutes and delts, but at an averagae of 2cc's in each glute a week with the proper pin and technique (22 guage-25 guage 1.5" 3ml), I am getting these big peach size bumps that are not going down as quick as when I first started. It takes a few weeks to totally disappear. Do you guys get these huge shot site swellings too?
